One of the major duties of the Japanese Army in Manchuria was to defend and maintain the South Manchurian Railroad. Here I will show some badges given to those soldiers and also some badges from the railroad itself.

The Rail Defense emblem has two varieties: One has crossed rifles superimposed on (or sometimes behind) a railroad tie and the other has axes and a tie. The former is a defense unit and the latter is an engineer unit, though their duties no doubt overlapped at times.
